We have multiple Windows 2003 terminal servers. We have configured group policy to end active but idle sessions after 1 hour. What is happening though is that users are kicked off the terminal server after about 5-10 idle minutes. They get no pop-up warning that their session will end, it just logs them off. They have to log back on and restart any programs that were open. I have checked the individual terminal services configuration and the Sessions tab for each user. There are no settings that would impose a shorter idle timeout. We're also getting no messages in the event log that corresponds to this. Any ideas?
